XTR117AIDGKRG4

Sensor And Detector Interfaces Overview

The XTR117AIDGKRG4 is a precision current-loop transmitter manufactured by Texas Instruments, designed to convert voltage inputs into a standardized 4-20mA output signal. It operates within a supply voltage range of 7.5V to 40V and draws a typical operating supply current of 130µA. The device supports both loop-powered and externally powered configurations, featuring an internal reference for excitation sources. It is housed in an 8-VSSOP package with an industrial operating temperature range spanning from -40°C to +125°C. This component integrates bridge excitation capabilities and linearization functions suitable for sensor interface applications.

Sensor And Detector Interfaces Feature Summary

• Integrates precision voltage-to-current conversion for standard 4-20mA industrial communication protocols
• Provides internal excitation voltage sources compatible with resistive sensors such as RTDs and bridges
• Supports flexible power architectures allowing operation in both loop-powered and external supply modes

Sensor And Detector Interfaces Applications

• Industrial process control systems requiring remote sensor signal transmission
• Bridge sensor conditioning circuits for strain gauges and pressure transducers
• RTD temperature measurement interfaces requiring integrated excitation

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS3 adherence when sourcing. Confirm the package type matches the required PCB footprint, as the VSSOP-8 form factor has specific soldering thermal profiles. Cross-reference the manufacturer part number against official distributor databases to ensure authenticity and traceability of the Texas Instruments component.

Sensor And Detector Interfaces Selection Notes

Select this component when a single-chip solution for voltage input to 4-20mA conversion is required without external isolation. Ensure the application supply voltage remains within the 7.5V to 40V operational window. Consider the 130µA quiescent current if battery life or low-power constraints are critical design parameters for the target system.

Sensor And Detector Interfaces Part Context

This part belongs to the XTR117 family of current transmitters from Texas Instruments. It serves as a specialized interface IC for connecting analog sensors to industrial control networks. The device simplifies circuit design by combining amplification, linearization, and current drive functions into a compact surface-mount package, reducing the bill of materials for sensor nodes.

Sensor And Detector Interfaces Replacement Considerations

The XTR117AIDGKR is a recommended replacement with identical functional specifications. Verify pin compatibility and package dimensions before substitution. Other family members like the XTR115 offer similar current loop functionality but may differ in excitation features or accuracy grades.
